Colorectal cancer

Latest evidence

The research team at Imperial College London produced an updated systematic literature review (SLR) of the evidence on food, nutrition and physical activity in relation to the prevention of colorectal cancer in 2010. The CUP review included 263 new papers that were identified in the CUP updated search.

The Expert Panel considered the updated evidence and agreed that the updated CUP findings confirmed or strengthened the convincing and probable conclusions of the Second Expert Report for colorectal cancer. The Panel agreed that the evidence for a protective effect from foods containing dietary fibre had strengthened could be upgraded to convincing. Conclusions for other factors previously judged to be convincing or probable were confirmed.

The Colorectal Cancer 2011 Report updates the colorectal cancer section of the Second Expert Report (section 7.9) and is based on the findings of the 2010 SLR and the Expert Panel discussion.

Eight journal papers based on evidence presented in the 2010 SLR and more recent analyses have been published.
